The performance pocket 1600 mattress provides the perfect blend of medical grade foam and traditional pocket springs, forming an excellent hybrid that ensures all the support and comfort needed for a well-balanced sleep. With regular tension, the performance mattress is not too firm and not too soft, a perfect compromise of both preferences.

Foam encapsulated, the mattresses sides have a strengthened edge, preventing any roll off whilst also increasing its overall lifespan. Covered in a smart, all natural Tencel material, the performance 1600 is excellent at controlling heat and moisture within the mattress.

A mattress aimed at the athletic, higher levels of support are found in the lumbar region ensuring your hips and back remain perfectly supported, helping to prevent aches and pains. This mattress is fully endorsed by numerous sporting bodies and medial groups, as well as being scientifically proven to enable quicker body recovering and ease of sleeping.
